SCRH2D14-100 Equivalent & Substitute Parts

Part Overview

The SCRH2D14-100 is a 10 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 710 mA continuous current with a maximum DC resistance of 396mOhm. This component is designed for applications requiring compact, shielded inductance in nonstandard package configurations. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH2D14-100 is determined by the following critical parameters:

Inductance Value: Must be 10 µH with ±30% tolerance
Current Rating: Substitute must support minimum 650 mA continuous current (accounting for design margin below the original 710 mA rating)
DC Resistance: Maximum 400mOhm to maintain circuit performance within acceptable limits
Shielding: Must be shielded to prevent electromagnetic interference in the target application
Operating Temperature: Must support the -40°C to 100°C range minimum
Mounting Type: Surface mount configuration required
Compliance: RoHS3 compliance and MSL 1 rating required

The CDRH2D11NP-100NC from Sumida America Components Inc. meets these substitution criteria with equivalent inductance, compatible current handling, and compliant certifications.

Engineering Selection Recommendations

The CDRH2D11NP-100NC qualifies as a functional substitute for the SCRH2D14-100 based on matching inductance value, equivalent DC resistance, identical shielding configuration, and full RoHS3 compliance with MSL 1 rating. Both components are Active status products suitable for production use.

Selection between the main part and substitute should account for the following differences:

Current Margin: The substitute is rated 60 mA lower (650 mA vs. 710 mA). Applications operating near the upper current limit of the original part require verification that the substitute's 650 mA rating remains adequate.
Saturation Current: The substitute exhibits saturation at 350 mA compared to 700 mA for the main part. Circuits sensitive to inductor saturation behavior must be evaluated against the substitute's lower saturation threshold.
Temperature Range: The substitute supports -40°C to 100°C versus -40°C to 125°C for the original. Applications requiring operation above 100°C must use the main part.
Physical Dimensions: The substitute is smaller (3.00mm × 3.00mm × 1.10mm vs. 3.20mm × 3.20mm × 1.55mm), offering potential PCB layout advantages with no functional penalty.

Both parts carry identical compliance certifications and are suitable for direct substitution in applications where the noted parameter differences do not impose functional constraints.

Frequently Asked Questions (FAQ)

Q: Can CDRH2D11NP-100NC replace SCRH2D14-100 in all applications?

A: The substitute is functionally equivalent for inductance and DC resistance characteristics. However, applications requiring continuous current above 650 mA, operating temperatures above 100°C, or sensitive to inductor saturation behavior at currents above 350 mA must retain the original SCRH2D14-100.

Q: What is the significance of the different saturation current ratings?

A: Saturation current indicates the point at which the inductor's inductance begins to degrade under increasing current. The SCRH2D14-100 saturates at 700 mA while the CDRH2D11NP-100NC saturates at 350 mA. Circuits operating in the 350–700 mA range may experience different inductance behavior between the two parts.

Q: Are the packaging formats interchangeable?

A: The main part is supplied in Tape & Reel (TR) format while the substitute uses Cut Tape (CT) & Digi-Reel® packaging. Both formats are standard surface mount packaging; however, assembly line equipment compatibility and handling procedures may differ. Verify your manufacturing process supports the substitute's packaging format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SCRH2D14-100 and CDRH2D11NP-100NC are RoHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified under ECCN EAR99 with identical HTSUS code 8504.50.8000.

Q: What is the practical impact of the smaller physical dimensions of the substitute?

A: The CDRH2D11NP-100NC measures 3.00mm × 3.00mm × 1.10mm compared to 3.20mm × 3.20mm × 1.55mm for the original. The smaller footprint and height may provide PCB layout flexibility without affecting electrical performance, provided current and temperature requirements remain within the substitute's rated limits.
